Logging can be a source of income at your Dharma center, and from the Dharma perspective, it has tremendous benefit. Of course, we don't cut all the trees, but are considerate in our selection. By doing this we are able to build statues, gompas, fund prayer wheels, etc. These things can help sentient beings create the cause for happiness. If sentient beings don't create the cause for happiness, ie wisdom, compassion, ethics, and concentration, then no matter how many beautiful trees there are, there is no happiness in the mind. So, by using the money created by doing some logging at a center we create long term benefit for sentient beings: liberation and enlightenment.
